Area of shallow flooding means a designated AO or AH Zone on a community's Flood Insurance Rate Map (FIRM) with one percent or greater annual chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate; and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
Easement Area means the area of the servient lot marked on the survey-strata plan as being subject to the relevant easement; and
Commencement of Commercial Production means:
(i) if a mill is located on the Property, the last day of a period of 40 consecutive days in which, for not less than 30 days, the mill processed ore from the Property at 60% of its rated concentrating capacity; or
(ii) if a mill is not located on the Property, the last day of a period of 30 consecutive days during which ore has been shipped from the Property on a reasonably regular basis for the purpose of earning revenues, but any period of time during which ore or concentrate is shipped from the Property for testing purposes, or during which milling operations are undertaken as initial tune-up, shall not be taken into account in determining the date of Commencement of Commercial Production;
Drainage means the movement of water to a place of disposal, whether by way of the natural characteristics of the ground surface or by artificial means;
ILUA Area means the geographical area in relation to which the Framework ILUA applies, as specified in Schedule 2 of the Framework ILUA;
impermeable surface means a surface or pavement constructed and maintained to a standard sufficient to prevent the transmission of liquids beyond the pavement surface, and should be read in conjunction with the term “sealed drainage system” (below).

Monitoring frequencies for sewage sludge parameters are based on the reported sludge weight generated in a calendar year (use the most recent calendar year data when the NPDES permit is up for renewal).
